Title (EN) FLEXIBLE FORM MEMBER AND METHOD OF FORMING THROUGH HOLE BY MEANS OF THE FORM MEMBER
(FR) ELEMENT DE MOULAGE SOUPLE ET PROCEDE DE REALISATION D'UN TROU TRAVERSANT AU MOYEN DUDIT ELEMENT DE MOULAGE
Abstract: front page image
(EN)A flexible form member according to the invention comprises a hollow-shaped body having a flexibility and openable fluid introducing and discharging means for permitting fluid to be introduced into and discharged from the body. A method of forming a through hole by means of the flexible form member comprises placing the flexible form member as contracted in a desired position between an outer form and an inner form, introducing fluid into the flexible form member to expand it between the outer form and the inner form, pouring concrete, removing the forms and contracting the flexible form member after curing of concrete, and removing the flexible form member thus contracted from concrete.
(FR)L'élément de moulage souple selon l'invention est constitué d'un corps creux souple pourvu de moyens ouvrables d'introduction et de décharge de fluide permettant l'introduction d'un fluide dans ledit corps ou la décharge dudit fluide de ce corps. Un procédé permettant de réaliser un trou traversant au moyen dudit élément de moulage consiste à placer celui-ci, lorsqu'il est dégonflé, à un emplacement désiré entre un moule extérieur et un moule intérieur, à introduire un fluide dans ledit élément souple de moulage pour le gonfler entre le moule extérieur et le moule intérieur, à couler du béton, à enlever les moules et à dégonfler l'élément de moulage souple après le durcissement du béton, et enfin, à retirer du béton l'élément de moulage souple ainsi dégonflé.
